I have been using Rotella T 15-40 in my 7060 forever and see that it is no longer available. It appears to have been replaced by T4 which I see has different specifications. I can't find anywhere on the Shell site whether or not I can use the T I have left with the new T4. Does anyone know if the oils can be used together, please? I sure don't want to mess my engine up to save $20 but I hate to dump new oil.

Mix em, the new oil is formulated for the modern EPA engines with catalytic converters so they lowered the zinc and added other anti wear additives. Was told many yrs couldnt mix synthetic and mineral oil, then they come out with a blend.
